RAG-CUTTING MACHINE.

SPECIFICATION forming part of Letters latent No. 286,373, dated October 9, 1883.

Application filed September 6, 1883. (No model.) Patented in Germany April :5, 1882, No. 20,328, and in Austria-Hungary September 12, 1889, No. 19,082.

To all whom it concern:

Be it known that I, LOUISBAUMANN, residing at Offenburg, in the Empire of Germany,

have invented new and useful Improvements in Rag-Cutting Machines, of which the following is a specification.

The object 'of my invention is to provide a new and improved machine for cutting rags very finely preparatory to converting them into paper-pulp.

The invention consists in a rag-cutting machine having a reciprocating knife which isconnected by a pivoted linlfivith the machineframe, whereby an oscillatory reciprocating movement is given to the knife, which thus makes a vertical shearing out.

The invention also consists in various parts and. details and combinations of the same, as

will be fully set forth and described hereinafter.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of my improved rag-cutting machine; Fig. 2 is a longitudinal elevation of the same. Fig.3 is a detailcross sectional elevation of part of the same.

The main shaft A is journaled in the top of a standard, B, and in a bracket-arm, C, of, the

u said standard, and between the standard and the end of the arma loose and a fixed beltpulley, D D, are mounted on the shaft, which is also provided with a fly-wheel, E. On one end the shaft A is provided with a crank, F, on the pin of which the upper end of the T-' Y shaped knife-beam G is fitted, the ends of the cross-piece of the knife-beam being guided by vertical guides H on theframe B. The knife J is bolted to the knife-beam G. A connectinglink, K, is pivoted to the knife-beam G and to the frame B. The rags rest on a bed plate,

L, along the edge of which the knife J cuts. Directly above the bed-plate a feeding roller, M, is journaled, whichis grooved longitudinally, or provided. with ribs, or roughened in any suitable manner.

On one end of the shaft of the feed-roller M a ratchet-wheel, N, is mounted, with which a pawl, O, is adapted to engage, which pawl is pivoted in one end of a rocking lever, P, pivoted on the shaft of the feed-roller. To the opposite end of the lever P a connecting- -rod, Q, is held adjustably, the upper end of which rod is held adjustably in a transverse groove, R, in the flat surface of a bevel cogwheel, S, engaging with a beveled cog-wheel, T, on that end of the shaft A opposite the oneon which the crank F is fixed.

justed to feed a greater or less length ofthe rags after each cut.

My improved rag-cutting machine requires less power than the machines for a like purpose that have been used heretofore.

Having thus described my invention, I claim as new and desireto secure by Letters Patent 1. A rag-cutting machine having a reciprocating knifebeani connected by a link with the frame of the machine, whereby an oscillatory reciprocating motionis given to the knife,- v

substantially as herein shown and described.

2, In a rag-cutting machine, the combination, with the driving-shaft A, of the knifebeam G, reciprocated by the same, and of the link K, pivoted to the frame of the machine and to the knife-beam, substantially as'herein shown and described.

3. In a rag-cutting machine, the combina tion, with the standard 13, of the shaft A, the

beam and to the standard, and of the verticalguides H, substantially as herein shown and described.

4. In a rag-cutter, the combination, with the shaft A, of the knife-beam G, worked from the same, and of the feed-roller M, also worked 6 knife-beam G, the link K, pivoted to the knifefrom the shaft A, substantially as herein shown the ratchet-wheel N, the pawl O, the lever P, and described. the bevel cog-wheels S and T, and the con- 5. In a rag-cutting machine, the conibinanecting-rod Q, held-adjustably on the bevel 15 tion, with the shaft A and the knifebean1 G, cog-wheel T and on the lever P, substantially 5 worked from the same, of the feed-roller M, as herein shown and described.

the rachet-wheel N, the lever I, the pawl O, In testimony whereofl have signed my name the connecting rod Q, and the bevel cogto this specification in the presence of two subwheels S and T, substantially as herein shown scribing witnesses. j and described. LOUIS BAUMANN.
